The invention has relation to grates for open fire-places, having forits object the provision of a grate detachably mounted on trunnions inan inclosing frame or fire place lining and all the parts of which maybe conveniently knocked down and packed in small space for shipmentetc., and which may be set up or assembled without the use of bolts orscrews in a short time by an unskilled Workman or boy.

Other objects and advantages will hereinafter appear.

The invention consists in the novel construction and combinations ofparts as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letters a,a, designate the two side frame pieces of the grate inclosure or liningof the fire place, having rear vertical slideways a, a, 0 en at the topand forming a seat for the fire back 0, said frame pieces havinginclined upper edges a a provided with lugs a ,c forming slideways orseats also open at the top for the inclined top piece 1), rear lugs c,c, forming means of connection with the back piece (Z, below the fireback; front lugs e, c, forming means of connection with the front framepiece f; inner lugs g, g, having slots g, 9, open at the topsthereof'for the reception of the trunnions h, h, of the grate 7t; andinner stop lugs 11, '5, adapted for engagement with the grate tomaintain it in normal position.

In assembling the parts the back piece d, which has lateral forwardextending flanges d, cl, provided with notches d (Z is first connectedwith one side frame piece a, and then. with the other side frame piece,such part a, being brought against the back piece insuch manner that therear inward extending lug 0, thereof will engage with a notch. (P, of aflange (1, when by turning the part a, outward the lug 0, will turntherewith into engagement with the rear of the back piece and the flange(1, will be brought against the outer lateral face of the side frame tolimit the outward movement thereof, both parts being then at rightangles to each. other. The fire back 0, is then dropped into position inthe seat or slideways a, a, resting upon a top flange d, of the backpiece and acting to further brace the side frame pieces a, a, againstoutwari'l movement. The inclined top I), is then slid downward in theslideways formed by the inward extending lugs a, 0;", until it abuts atits lower edge against the fire back, said top having lateral grooves b,l), in its under face, having on gagement with the upper inclined edgesof the side frames, and a narrow horizontal top flange 6 also groovedlaterally on its under face in continuation of the grooves l), b, andacting to limit the downward. movement of the top. The side frames arethus additionally secured against outward movement and at the same timebraced against inward movement. The frame thus formed is now tiltedrearward and the front piece f, being brought into position is drawnupward until the wedge-form dove-tail lugs f, f, which project from itsinner face are engaged with seats of similar formation in the front lugse, e, of the side frames when, the parts being lowered to the ground,the whole frame is securely locked together so that separation ormovement of the parts thereof cannot take place. The front piece when inposition in the lining frame abuts against the top piece to preventupward slidable movement thereof. 7

The top piece I), is provided with a line of openings If, at the lowerportion thereof, such openings being controlled by a reciprocatorydamper plate j, having a line of simi lar openings y", and beingoperated by a horizontal rotatable rod j", having an arcuate slottedright-angle end-extension 9' having engagement with a lug j, of thedamper 4 plate, said lug having its outer end portion formed withopposite notches j, j", which are engaged by the arcuate end 1' of theoperating rod, the neck portion j, of the lug connecting the lug properwith the T-forni head 9' thereof fitting in the slot of the end exten=sion 7' Thus upon rotation of the rod the arcuate end extension y, willbear against the end Walls of the notches j 7"", in the man.- ner of acam, and will act to force the damper to open or closed position as thecase may be. This operating rod has bearings in an outward extending lugof one of the side frame pieces and in a perforation of the front piece.I 1

At the upper portion. of the top piece I), an

' opening 7:, extending entirely across the sanie, is provided, suchopening being controlled by a pivoted damper 76, having end pivotextensions k provided with bearings in lugs k of the top piece, one'ofsaid lugs 7?, having a stop extension k against which the damper isdesigned to rest in entirely open position thereof.

An operating rod Z, is provided with a slot Z, at its rear end portionhaving engagement with a laterally extending lug Z of the damper,thislug being provided with opposite notches Z Z, a T-form head Z, and aneck portion Z connecting such head with the body of the lug and lyingat the bottom of the opposite notches. Upon endwise movev ment of therod Z, an end wall of the slot Z,

will engage the neck portion Z of lug Z, to open or close the damper.The damper may be held partly open by means of engagement of rackteeth'm, of the rod with a tooth m, formed in the bottom of the openingm of the front frame piece through which opening the rod passes.

In order to place damper late j, and its operating rod 3' in position, te crooked rod handle is first passed from the rear through theperforation f of the front piece and the oppositely notched part n,thereof let down into the contracted slot or opening in the top of lug fwhen upon pushing the rod slightly same plane as or in register with theslot 7' of the extension j when the notched end of the lug may be pushedwithin said slot, and

the dam er late bein turned to one side,

P P z:

the opposite notches of the lug will at the same time pass intoengagement with the branches j of the extension 7' and the neck portion3', into engagement with the slot 7'". "he damper plate may be thenpressed up ward into engagement with lugs 0, of the top frame piece, andbeing let fall, will drop into engagement with lugs 0, of the top piecewithout escaping from the downturned ends of the lugs 0. The damper Zr,may now be added, and to this end the operating rod Z, thereof is firstpushed through the opening m of the front frame piece. The damper isthen turned so that the flattened lug Z'-, thereof will lie in the sameplane as or register with the slot Z, of the rod, when the notched endof the lug may be pushed within the slot and the damper being turned toone side the op posite notches of the lug will pass into en- 'a ementwith the rod and the neck ortion a b sion k is dropped into engagementwith the other lug k The grate basket h, being passed into the fireplace is let down in such manner that the pivot studs or trunnions h, atthe ends thereof drop into open top slots g, of bearing lugs g, of theside frame pieces. The major part of the weight of the grate basketbeing forward thereof it will drop automatically to normal loweredposition when the front part of the grate will lie in engagement withthe stop lugs i, i, of the side frame pieces.

It will be noted that when the parts are assembled, the last piece addedto the frame, namely the front frame piece, locks the entire frametogether and is held in position by the weight of the castings,rendering it impossible for the parts to become separated after beingonce set in position.

The grate basket rests on pivots or trunnions carried by upwardextending end arms lying above the horizontal grate bars andintermediate of the height of the vertical front "bars of the basket,whereby it is balanced to turn upward easily upon its pivots, fordumping purposes, and returns to normal position automatically. 7 1

The dampers enablethe fire to be quickly started and at the same timeperfectly controlled, the upper damper serving as the usual regulator ofthe heat and draft and the lower damper for fire starting purposes.

All parts of the invention are designed and adapted to be made of castiron with the exception of the fire back, which is made of fire clay orother suitable refractory material.
